## What it is
CubicSDR is a cross-platform software-defined radio (SDR) application with an OpenGL-accelerated spectrum and waterfall display. It supports a wide range of SDR hardware including RTL-SDR, HackRF, Airspy, SDRplay, PlutoSDR, and any device supported by SoapySDR.

## Use cases
- listen to FM/AM radio broadcasts with an RTL-SDR dongle
- monitor ham radio frequencies and bands
- view a live spectrum analyzer and waterfall of RF signals
- receive weather satellite or aircraft ADS-B transmissions
- demodulate narrowband voice channels from SDR hardware
- explore the radio spectrum across wide bandwidths with a HackRF

## When to choose
- you want a ready-to-use GUI for SDR reception on Windows, macOS, or Linux
- you need broad hardware support through SoapySDR drivers
- you want visual spectrum and waterfall displays with GPU acceleration

## When to avoid
- you need headless or scripted signal processing rather than a GUI
- you require advanced digital mode decoding built in (use dedicated decoders alongside)
- you need a lightweight tool for embedded devices with limited GPU resources

## Facets
- artifact type: application
- maturity: stable
- function: audio-processing, image-processing, gui, data-visualization
- domain: hardware, cross-platform, developer-tools
- platform: windows, cross-platform, cpp
- tags: software-defined-radio, sdr, rtl-sdr, spectrum-analyzer, ham-radio, opengl, soapysdr, signal-processing, radio-scanner, linux, macos
